Ultrafast Laser Line Mirror is an indispensable core component in femtosecond and picosecond laser systems. By using a dedicated ultrafast mirror, you no longer need to worry about the "three major concerns": Are standard mirrors suitable for ultrashort pulse lasers? Can they fully preserve the temporal characteristics of the laser beam? Can they withstand extremely high peak intensities? This series of mirrors eliminates these concerns through multi-band design, low dispersion optimization, and high-density coatings.

Firstly, this series of mirrors offers various band combinations upon request, such as 1064 + 532 nm, 1030 + 515 nm, and even three-band 2940 + 1535 + 535 nm, catering to diverse needs from near-infrared to visible and even mid-infrared. Using advanced Ion Beam Sputtering (IBS) coating technology, we precisely control Group Delay Dispersion (GDD) to <10 fs², ensuring that femtosecond pulses experience almost zero temporal broadening before and after the mirror, perfectly preserving the temporal structure and phase information of sub-100 femtosecond pulses. Meanwhile, reflectivity within the design wavelength range can reach >99.8%, and it maintains a transmittance of >90% outside the working wavelength range, ensuring the flexibility and efficiency of energy distribution in the system.

Secondly, IBS coatings have extremely high density and excellent adhesion, effectively resisting drastic changes in temperature, humidity, and vacuum environments, ensuring that the reflective properties remain stable and drift-free over time. Under high peak energy, the Laser Induced Damage Threshold (LIDT) of this series of mirrors can reach >3 J/cm² (10 ns single pulse), and it still performs reliably under high repetition frequency and high average power conditions. Its superior environmental adaptability and high damage threshold make it not only crucial in research-grade ultrafast spectroscopy, time-resolved experiments, and chirped pulse amplification (CPA) systems, but also highly applicable in industrial ultrafast laser processing, high-speed precision marking, and other applications, providing higher efficiency and more stable performance for your system.

Precautions: To ensure optimal performance, it is recommended to store and use the mirror in an environment at 25°C with a relative humidity of 40%–60%. If the mirror surface becomes contaminated, gently wipe it with 99% or higher alcohol and a lint-free lens cleaning tissue. Avoid using rough fabrics, water, or cleaning agents containing abrasive particles, as they may damage the coating.
